Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Monitoring cameras face challenges with processing power requirements exceeding limited power supplies, leading to insufficient energy for high-performance image processing, especially in scenarios like temporary installations or low PoE classes.
Innovation Solution
A method for controlling monitoring cameras that utilizes an external power source and an energy accumulator to dynamically adjust processing states based on detected events, allowing for increased power levels beyond the external maximum, optimizing image processing capacity and extending battery life by charging the accumulator during periods of low demand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the monitoring camera uses high processing power to handle complex image processing requirements, then the image processing capability is improved, but the power consumption increases beyond the limited power supply capacity
Solution Approach 1:
The camera dynamically adjusts its processing state based on detected events. During normal operation, it uses low-power first processing state. When an event is detected, it transitions to high-performance second processing state only when sufficient energy is available in the accumulator, allowing the system to adapt its processing capability to available power resources.
Solution Approach 2:
The system pre-charges the energy accumulator during periods when power consumption is low (normal monitoring without events). This preliminary energy accumulation enables the camera to temporarily access high processing power when events occur, without exceeding the average power supply limits.
2Adaptability or versatility
If the monitoring camera operates in temporary installation with limited power supply, then the installation flexibility is improved, but the processing power becomes insufficient for high-demand scenarios
Solution Approach 1:
The system pre-charges the energy accumulator during low-power periods to enable temporary high-performance operation when events occur, allowing temporary installations to access high processing power without requiring high continuous power supply infrastructure.
Solution Approach 2:
The system changes operational parameters by switching between first processing state (low power) and second processing state (high power) based on event detection and energy availability, allowing the same hardware to deliver different performance levels according to instantaneous power availability.
3Ease of operation
If the monitoring camera uses low PoE class to ensure compatibility and basic operation, then the ease of deployment is improved, but the processing power is insufficient when events require high-performance analysis
Solution Approach 1:
The camera accumulates energy in advance during normal operation with limited PoE power, enabling it to temporarily access high processing power when events occur, thus maintaining ease of deployment with low PoE class while still delivering high processing capability when needed.
Solution Approach 2:
The system dynamically scales processing power based on event detection and energy availability, allowing it to operate at low power during normal conditions (ensuring compatibility) and temporarily access high power for event analysis (improving processing capability) without requiring high PoE class infrastructure.

AI summary
A monitoring camera is connected to an external power source. The external power source has an external maximum power level. Image data is being processed in a first processing state. The monitoring camera detects (202) an event and determines (206) a type of the detected event. An amount of energy in an energy accumulator is determined (208) in the monitoring camera. Based on the type of the event and based on the external maximum power level and based on the determined amount of energy in the energy accumulator, a second processing state is determined (210). The second processing state requires a power level that is higher than the external maximum power level. Image data is then processed (212) in the second processing state.
